this update allows to use registers map as following :
regs[reg_index + offset] instead of
regs[reg_index] + offsetThis makes code clearer and will facilitate the addition of STMPE1600
on which LSB and MSB registers are respectively located at addr and addr + 1.
Despite for all others STMPE variant, LSB and MSB registers are respectively
located in reverse order at addr + 1 and addr.For variant which have 3 registers's bank, we use LSB,CSB and MSB indexes
which contains respectively LSB (or LOW), CSB (or MID) and MSB (or HIGH)
register addresses (STMPE1801/STMPE24xx).
For variant which have 2 registers's bank, we use LSB and CSB indexes only.
In this case the CSB index contains the MSB regs address (STMPE 1601).Signed-off-by: Patrice Chotard

In order to prepare the ground to STMPE1600,
as STMPE1600's SYS_CTRL register has the same layout as
STMPE801 variant, unify STMPExxx_REG_SYS_CTRL_RESET/INT_EN/INT_HI
bit masks to more generic STMPE_SYS_CTRL_RESET/INT_EN/INT_HISigned-off-by: Patrice Chotard

Reset was only implemented for STMPE1801 variant despite
all variant have a SOFT_RESET bit.For STMPE2401/2403/801/1601/1801 SOFT_RESET bit is bit 7
of SYS_CTRL register.
For STMPE610/811 (which have the same variant id) SOFT_RESET
bit is bit 1 of SYS_CTRL register.Signed-off-by: Patrice Chotard

As STMPE1801/1601/24xx has a SYS_CTRL register and
STMPE1601/2403 has even a SYS_CTRL2 register, add
STMPE_IDX_SYS_CTRL/2 and update driver code accordinglyThis update prepares the ground for not yet supported STMPE1600
which share similar REG_SYS_CTRL register.Signed-off-by: Patrice Chotard

The STMPE driver would just read/modify/write the system control
register on the STMPE1601, meaning it would not properly mask off
the PWM block, which remained active if it was on at boot time.
This makes sure the blocks are always masked off if they were
active on boot, saving some power. Also rename the inconsistenty
named STMPE1601 define for the PWM block activation.Signed-off-by: Linus Walleij

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.Signed-off-by: Geert Uytterhoeven

Few STMPE controller can have register interface over SPI or I2C. Current
implementation only supports I2C and all code is present in a single file
stmpe.c. It would be better to separate out I2C interface specific code from
controller specific code. Later SPI specific code can be added in a separate
file.This patch separates out I2C and controller specific code into separate files,
making stmpe.c independent of I2C.Signed-off-by: Viresh Kumar
